This invention relates to apparatus for separating adherent yarns suchas may occur in a sheet of warp and, more especially, this inventionrelates to an improved automatic rake for separating adherent yarns asthey are processed.

on a quilling machine or the like.

Heretofore, many attempts have been made to perfect a suitable apparatusfor raking or strumming a sheet of parallel yarns such as a sheet ofwarp yarns, for separating the individual yarns from each other inadvance of the sheet passing through the usual reed in its course to thequills on the spindles of a quilling machine or to a warp on a longchain beamer. However, there have been many disadvantages in the rakingdevices heretofore employed such as, for example, some quilling machineshave been provided with a reciprocating member having fingers thereonfor raking the warp yarns for separating the same and including amechanical driving means for the reciprocating member of a type whichwas necessarily noisy due to intermeshing pinions and other movingelements.

Associated with most quilling machines is a turntable or container whichis disposed adjacent the usual platform on which the operator standsduring operation of the quilling machine. The yarn usually passesupwardly from the container in the form of a rope of untwisted parallelyarns, and then passes above the operator and the quilling machine andrearwardly to a tailstock including a pair of parallel idler cylindersabout which the rope of yarns passes several times. The yarns then wouldfan outwardly in warp form to the usual reed of the quilling machine tobe wound about the quills on the spindles of the machine. The quills areusually frictionally supported by the driven spindles thus enabling anoperator to grasp the rope of yarns to retard its movement which, ofcourse, would cause the quills to rotate at a slower speed than thespindles on which they are mounted.

Heretofore, at least one form of quill raking mechanism has been drivenby means of a mechanical connection with the cylinders of the tailstockwith the result that, upon the operator grasping the rope of yarns forretarding movement thereof, the raking device would operate at arelatively slow speed thus rendering the same inefficient in itsoperation. In other words, another disadvantage of some types of rakingdevices heretofore in use is that the raking means has been driveneither in a reciprocatory or rotary manner at a speed proportionate tothe speed at which the warp yarns were taken up by the quills after theyhad passed through the usual reed. Thus, upon an unfavorable conditionof the yarn, such as, upon a plurality of adherent or intertwisted yarnsapproaching the reed, the operator would either stop the machine or, bygrasping the rope of yarns, would allow the warp yarns to pass throughthe reed at a relatively slow rate so they would not break. It isevident that, if the raking means was driven proportionately to thespeed at which the yarns passed through the reed, then the raking meanswould slow down as the speed of the warp yarns was slowed down therebydecreasing the effectiveness of the raking means when it would be mostimportant that the raking means should operate at its normal speed.

It is, therefore, the primary object of this invention to overcome suchdefects, as well as many other defects apparent to those familiar withthe art, by providing an improved raking device for quilling machineswhich is so designed as to be positioned immediately beneath the sheetof warp yarns at a point in advance of the usual reed and including amember having a plurality of closely spaced radially extending fingersthereon, wherein an improved means is provided for driving the memberhaving the fingers thereon in a reciprocatory manner excluding anyintermeshing mechanical driving devices, such as pinions and the like,and the driving means being operated independently of the means fortaking up the yarn, such as the frictionally driven quills, but whichdriving means, on the other hand, is rendered operable automatically tostop and start simultaneously with the stopping and starting of themachine.

It is another object of this invention to provide an improved rakingdevice for quilling machines which may be economically constructed andmaintained, which is also efliciently effective in separating adherentyarns and is simple to operate.

It is still another object of this invention to provide an improvedraking device for quilling machines comprising an elongated tubular memiher or cylinder having a pair of longitudinally spaced pistons thereinand opposite ends of the cylinder being closed. The pistons are fixed tothe proximate ends of rigid stationary conduits or tubular piston rodswhich extend outwardly substantially from the corresponding pistons andare fixed on the frame of the machine. The outer ends of the tubularpiston rods have means for alternately directing fluid under pressure,such as compressed air, to one of the same while exhausting compressedair from the other of the same whereby the compressed air willalternately be introduced to opposite end portions of the cylinder andwill thereby cause the cylinder to reciprocate, the means for admittingcompressed air to the rigid conduits being controlled by manuallyoperable means which starts and stops the machine.

It is" still another object of this invention to provide an improvedraking device of the character last described with means forautomatically rotating the elongated tubular member or. cylinder havingthe fingers thereon in one direction for a partial revolutioneach-timethe machine is stopped and for also automatically rotating thepiston a partial revolution in the opposite direction each time themachine is st arted whereby the fingers on the piston may be sopositioned as to move with the piston out of engagement with the warpyarns as the machine is stopped or operated at a relatively ;S1OW,speed, thereby facilitating the piecing togetherof broken ends.orotherwise permitting the operator to. manipulatethe warp yarns.without being encumbered by the. raking; fingers and, whereby,upon'starting the machine and operating the same at its, normal high.speed, the fingers will again automatically Hmoveinto position for,engaging the ,warp yarns as,,longitudinal reciprocatory movement isimparted tothe. cylinder to thereby effectively separate adherent, ya

Ofcourse it is, evident that the machinemay ,bestarted and operated at arelatively slow speed and subsequently. stoppedv without the rakingfingers having moved intoengagement with the warp yarns and, as amatteroffact, the spindles and thev corresponding quills may be operatedat an intermediate high speed wherein the fingers would be disposedclosely adjacent the warp yarns but wouldnot be in engagement therewith,the purpose of which. will. i be. later described.

Some of the objects of the invention having been stated, other objectswill appear as the description proceeds when taken in connection Iwiththe accompanymg drawings, in which- Figure l. is a, right-hand side,elevation of a typical quinine. m c in showing t imp d raking devicemounted thereon;

Referring morespecifically to the drawings, the improved rake or yarnseparating means is shown mounted on a conventional vquiller or quillingmachine of usual construction. Considering the I manner in which theimproved raking device cooperateswith drivingmeans of the uillingmachine, a description-of the uill'lng machine will first begiven.

Referring toFigures-l, 2 and 3, it ,will betobserved that thecpiillingmachine comprises laterally spaced first and second side framemembers H] and H between whicha vertically disposed intermediateframemember i2 is disposed, these frame members it], I Landitirestingupon a floor F. The vertically disposed framemembers 19, H andI2 arebridged by suitable-horizontal frame members including ,a frame:member I 3 which is suitably secured tothe prosgirnate surfaces of theframe members-wand ll andis also secured to thedntermediate framernember E2.

The frame members in, -I I and. I2 aregalso.se cured in proper spacedrelation, to each. other'by upper framemembers-or tie'rods L5 and 1.5. 1-The vertically disposed frame members i0, ii and i2 are also spanned bya plurality of .angularly spaced horizontally disposed bolster orspindle rails l1 which are disposed at the front of the machine, or theleft-hand side of Figure 1, and each of which has a plurality oflongitudinally spaced spindles mounted for rotation thereon. Each of thespindles 20 has a suitable quill 2| positioned thereon to each of whichan individual strand of yarn Y is directed in a manner to be presentlydescribed. These spindles 20 are of usual construction and each has asuitable whorl 22 thereon which is engaged by a corresponding endlesstape or endless rope 23 for transmitting rotation thereto.

It is to be noted, in Figure 15, that the lower end of each quill restsupon a sleeve 20a rotatable relative to the spindle 20 and a friction orclutch ring 20b encircles the spindle 20 and is frictionally engaged bythe proximate surfaces of the whorl 22 and the sleeve 20a whereby thequill 2| may rotate at a slower speed than the spindle 20 and whorl 22.This may happen upon one of the yarns Y becoming unduly taut or all theyarns being slowed by the operator.

The endless tapes or ropes 23 extend rearwardly and partially encirclecorresponding cylinders 24 which are fixedly mounted on shafts 25 to 29,inclusive, there being two of the cylinders 24 mounted on each of theshafts 25 to 29 as is clearly shown in Figure 2. The remote ends of theshafts '26 to 29, inclusive, are rotatably mounted in suitable bearings32 suitably secured to the corresponding side frame members H) and II.The medial portions of the shafts 26 to 29 extend through theintermediate frame member 12. The specific structure of the cylinders 24and the corresponding shafts 25 to 29, inclusive, is a matter of choiceand a detailed description thereof is deemed unnecessary.

The shaft 25 is the main driving shaft of the machine and is journaledat one end thereof in a bearing block 34 which is suitably secured tothe side frame member I, the other end thereof penetrating a relativelylarge gear 35 which is suitably secured to the shaft 25 (Figure 2). Thisend of the shaft 25 also slidably penetrates a hub portion 36 of apinion 37 and has a main driv- .ing or high speed pulley 40 fixedlymounted adjacent the outer end thereof. The outer end of the shaft 25relative to the frame member in is rotatably mounted in a bearing block4|.

The bearing block 4| is fixed on the outer end of a substantiallyU-shaped bracket 42 which extends outwardly from the corresponding framemember H). The hub 36 of the gear 31 has a relatively narrow low speedpulley 43 fixedly mounted thereon, the diameter of which issubstantially the same as the high speed pulley 40. This hub 36 also hasan idler pulley 44 rotate ably mounted thereon and which is engaged by abelt 45 when the machine is at rest.

During normal operation of the machine, the belt 45, which is driven byany suitable means disposed above the machine and which has been omittedfrom the drawings, is positioned in engagement with the main driving orhigh speed pulley 40 substantially as shown in Figure 2. During periodsof relatively slow operation of the machine, the belt 45 is shifted intoengagement with the low speed pulley 43, by means to be presentlydescribed, whereupon the gear 31 will be driven by the pulley 43 torotate about the shaft 25.

Now, the pinion 3| engages a relatively large gear 4'! which is fixed onthe stub shaft mounted for rotation in the side frame member I 0. Thisshaft '50 extends through the side frame member In and has a pinion 5|fixed thereon which meshes with the relatively large gear 35 heretoforedescribedwhereby the pinion 31 will cause the relatively large gear 35to rotate at a substantially slower rate than is the case when the belt45 is in engagement with the high speed pulley 40. The pulley 40 beingfixed. on the shaft 25 causes the shaft 25 to rotate at a relativelyhigh speed. The drive shaft 25 drives the shafts 26 to 29, inclusive, bymeans of sprocket wheel and sprocket chain combinations indicatedgenerally at 52. It is thus seen that the quilling machine has.conventional means for varying the speed of the spindles 20 and thequills 2| thereon.

It will be observed in Figures 1, 3 and 6 that the individual strands ofyarn Y extend from an idler roll to which the yarns Y are directed inthe form of a sheet of warp yarns designated generally at As is wellknown to those familiar with the art, the sheet of warp yarns W usuallyoriginates in the form of a rope or chain of parallel untwisted yarns.Referring to Figures 13 and 14, the yarns, while in rope form areindicated generally at R. This rope of yarns R extends from a suitablecontainer or turn table 53 disposed forwardly of the quilling machineand within reach of the operator thereof and from whence the rope ofyarns R extends upwardly between a plurality of primary idler tensionrolls 53b rotatably mounted on a suitable support 530 suitably suspendedfrom above.

The rope R then extends over the machine and then rearwardly aboutsecondary idler tension rolls or cylinders 53d of a tailstock 530 alsosuitably suspended from above. After the rope has passed about the rolls53d a few times the yarns then extend forwardly and fan out to form thesheet of warp yarns W. The sheet of warp yarns W then passes through areed 56 to the roll '55. The reed 56 is of conventional construction andis mounted upon brackets 51 which extend downwardly and are suitablysecured to the inner or proximate surfaces of the side frame members Inand I] (Figure 2).

The reed is provided with a plurality of conventional vertical spacingpins 60 and, in their course from the source to the idler roll 55,individual yarns Y in the sheet of warp preferably pass betweenalternate spacing pins '60 to the idler roll 55 to thus separate thestrands of yarn Y in advance of their being directed to the quills 2|.The idler roll 55 is supported for rotation in suitable bearing blocks62 which are suitably secured to upwardly projecting portions Illa andIla of the respective side frame members I0 and l I.

As is well known to those familiar with the art, a quilling machinerequires the constant attention of an operator and these machines areusually provided with a suitable platform 63, only a portion ofwhich isshown schematically in Figures 1, 3 and 4, on which the operator standsduring operation of themachine. The operation of the machine iscontrolled by means of a treadle bar 64 which is positioned closelyadjacent the platform 63 and extends from adjacent the side frame memberI 0 to a point adjacent the side frame member ll.

This treadle bar is suitably secured to the front ends of a pair ofoperating levers 65 which extend rearwardly and downwardly and arefixedly mounted one, transverse shaft 66 whichis oscil- .57 wl'ata'blyrmounted im suitailele bearing blockwfil suitablysecured to 'theproximate'ssurtaces 'ofithe -side frame members 10 and l I.

The piston rods 9| and 92 slidably penetrate suitable closures orcylinder heads on respective ends of the cylinder It will be observed inFigure 9 that each of the closures or cylinder heads comprises anexternally threaded tubular member or collar I 20 which is fixedlymounted on the corresponding end of the tubular member or cylinder 90,as by welding, and extends substantially beyond said corresponding end.An annular washer I2I engages the corresponding end of the tubularmember or cylinder and is disposed within the portion of the tubularmember I which extends beyond the end of the cylinder 90.

There is also positioned within this member I20 corresponding tubularmember I 20. The gland nut I is loosely penetrated by the correspondingpiston rod 9| or 92 and the resilient washer I24 and the sealing memberI23 at each end of the cylinder 90 are slidably penetrated by thecorresponding piston rods SI and 92.

The proximate ends of the piston rods are connected to opposed ends of atie or splicing bar I21 which is shown as being polygonal incrosssection in Figure 11 but which may be of any desired configurationin cross-section. Suitable means are provided for keying the cylinder 90to the tie bar I21, Suitable pistons broadly designated at I and I3I(Figures 8 and 8-A), of any desired construction, are suitably securedto the proximate or lnnerends of the respective piston rods BI and 92and the cylinder 90 is mounted for longitudinal sliding movement on thepistons I30 and I3I.

In this instance, it will be observed in Figure 9 that a pair of rigidwashers I33 surfaces of which are engaged by the inner end of thecorresponding piston rod 9| or 92 and the tie or splicing bar I21. Thesplicing bar I21 has a reduced threaded portion I at each end thereof,only one end of which is shown in Figure 9, and each of these reducedends I35 of the tie bar I 21 slidably penetrates the washers I33 and I34and the cup I32and is threadably embedded in the end of thecorresponding piston rod 9| or 92.

The reduced portion I35 at each end of the tie bar I21 is tightened inthe threaded end of the piston rod 9| or 92 and is locked in position bya suitable locking pin I36. It will be observed that the proximate endsof the piston rods BI and 92 are each provided with one or moreapertures I31 therein for passage of compressed air therethrough as willbe later described.

Referring to Figures 8-A, l0 and 11, the cylinder carries a plurality oflongitudinally spaced radially extending substantially inverted U-shapedor V-shaped yarn or strand separating fingers I40 which are preferablyformed from a wire of relatively small cross-sectional diameter andopposed ends of each of which is suitably secured, as by bolts I M, toan elongated bar I 42 which is shown in the form of an angle bar inFigures 6 to 12, inclusive. This angle bar I 42 is secured to what isnormally the upper surface of the cylinder 90 by any suitable means suchas e, screw I43 which 18 disposed at the center of alinement with acentrally disposed guide block I44 disposed within the cylinder 90 andwhich is secured in the cylinder 90 by a suitable lubricant fitting I45.

The guide block I44 is mounted for longituditie splicing bar I21 toblock I 44 may slide ing bar I 21.

It will be observed in Figure 11 that the guide block I44 has aplurality of circularly spaced notches or passageways I41 in theperiphery thereof to permit surfaces of the 90, this Washer is spacedslightly riphery of the cylinder 90 for purposes to be presentlydescribed.

Opposed ends of the angle bar I42 are suitably secured to the tubularmembers I20 at opposed ends of the cylinder 90, as by screws I5I' and,

required so the bar I42 extends in a straight line.

In order to permit the resilient members I81 to pivotupwardly in the manner described, each of the resilient members I81 hasa notch I95 in the inner face thereof adjacent thebracket I9I, the wallsof which straddle the cylinder 90 when the resilient member I81 ispivoted inwardly and upwardly.

In operation, assuming the cylinder 90 to be moving from right to leftin Figure or from left to right in Figure 12, the resilient member I81associated with the valve actuating device I86 moves therewith and theinner surface thereof moves into the notch I160 in the valve controllever I16 and, thus, engages the corresponding wall thereof to cause thevalve control lever I16 to move from the solid line to the dotted lineposition shown in Figure 12. The valve core I BI will consequently berotated a quarter revolution to thereby position the passageway I62 inthe core I6I (Figure 10) in communication with the passageways I66 andI61 in the housing I6I'Ia and to position the passageway I63 incommunication with the passageways I54 and I65. Compressed air orfluidunder pressure will then pass from the pipe IN, to which it isadmitted in a manner tobe later described, through the passageways I61,I62 and I66, successively, and through the pipes I51 and I 54 to thetubular piston rod 92.

The compressed air will then be exhausted through the correspondingapertures I 31 into the space between the closure, including the glandnut I25 at the right-hand end of the cylinder 90 (Figure 8-B), and thepiston I3I (Figure 8-A). Since the piston I3I remains stationary,compressed air thus admitted to the cylinder 90 will cause the cylinder90 to move from left to right in Figures 8 to 10, inclusive.

Since this reverses the direction of movement of the cylinder 9!), thevalve actuating devices I35 and I 86 will move from left to right inFigure 10, or from right to left in Figure 12, and as the valveactuating device I86 moves from left to right in Figure 10, theresilient member I81 associated therewith will ride over the upper edgeof the valve control lever I16 in the manner heretofore described.Subsequently, the resilient member I 81 of the valve actuating deviceI85 will enter the notch I160 in the valve control lever I16 to againmove the valve control lever to the solid line position shown in Figures10 and 12 and to again cause the cylinder 90 to reverse its direction ofmovement.

This movement of the valve control lever I16 to the solid line positionshown in Figures 10 and 12 causes the passageways I62 and I63 in thevalve core I6I to assume the position shown in Figure 10 with the resultthat the compressed air will pass from the pipe I'II through the passageways I61, I62, and I 64, successively, through the pipes I56 and I53to enter the tubular piston rod 9|. The compressed air will then beexhausted through the corresponding apertures I31 thereby entering theleft-hand portion of the cylinder 90 between the closure at theleft-hand end thereof in Figure causing the cylinder '90 to moveiromright to 9 and the piston I32 thus 14 left in Figures 8 to 10,inclusive. air in cylinder at the right-hand end thereof will bedischarged through the apertures I31 in piston rod 92 at this time.

It is thus seen that the only audible sounds in the operation of thedevice is that of the compressed air being exhausted through the pipeI18 and, if so desired, the exhaust pipe I10 may exmaintenance thereofto a minimum in comparison to raking devices heretofore employed.

Now, in order to control the operation of the speed at whichreciprocatory movement is imparted to the cylinder 90. The pipe I H thenextends downwardly and passes through the lower portion of the sideframe member I I IN. is suitably secured to an angle bracket 2I0 whichis suitably secured, as by screws 2I I, to the inner surface of the sideframe member In (Figure 4).

The bracket 2I0 has a valve control lever 2I2 oscillatably mountedthereon, as at 2I3, which extends forwardly and the front end of whichhas an adjustment screw 2 threadably mounted there may be desirous thatthe sheet of warp forwardly at times when it is y rns W is peranintermediate with theielcw:speedw-pulleyr 432 (Figured) and d being inensuhstantialt-portion ofzthe belts gagement with ,the .high' speediplllley- Qilythe up per surface of the arm l3 "oirtheqhell'cranz l-l;will notthaveeffected upward movement of the adjustment screw :2 Ht.

It is essential that the raking device continues to operate atits-normalspeed during the tim m mrthatr the operator 2 andtheilcwerisgrasping the rope of yarns R, since it would be-iinconvenient for theoperator to separate these intertwined or adherent yarns-manually atthesame time that the operator is grasping the rope of yarns R; 1 Also,rapid re'ciprocation-ofathe raking fingers ltdwould be necessary atthis'time to insure that the raking. i

Also, it is l often necessary torithe operator to slow down-the movementof the sheet-of warp yarns, by means ofgrasping the rope of yarns R, inthe event thatsome .ofrthel individual yarns in the sheet'ofr warp yarnsW become abnormally the spacing pins fill of slack relative .to. theremaining or majority ,of v

Now, in order to. obtain maximum production in a day's time,. it is notunusualfor an operator to grasp the, rope, of yarnsR'at-varyingpressures to ,retard jmovement thereof,- accordingly. In

fact, the operator nearly, always grasps the rope However-,on certainoccasions, he. tightens theholdloriincreases his grasp of the l of yarnsR.

It will. be observed in Figures. 1 and 2 that the exhaust pipe [55extends outwardly from the valve housing [Bit and, then extendsforwardly past. thebearing, stand or standard 93 and then n a planeextends. downwardly and terminates i substantially intermediate theupper and lower ends, of theside frame, member [0. as. heretofore;stated, the. exhaust pipe be extended through the floor F to thus renderthe. sound of the escaping compressed air in audible to the; operator.

It is. extremely important that the quilling machine and. of course, theraking mechanism operate with the least possible amount of noise,

merely by removing the pipes I53 and I54 from theremote ends of thepistonrods 9| and 92 and then loosening the, nuts. I00 and ml or eitheroneotthenuts I00 and I 0| after which thepiston; rods 91-, and 92 liftedouter the standards Stand 94.

The:attitude of the raking fingers I40 may. be varied relativesto thevarious positions inwhich the treadle; bar 64: may be disposed byshifting theapositionofxthe sprocket chain l H relative to the sprocketwheel I I0 as desired.

Another-important feature of the present raking device isthe-uniqueconfiguration of the raking fingers I 40. As is well known tothose familiar with the art, many experienced quilling machine operatorsrest their forearms or hands upon the. reed 56: during operation of themachine and can often determine when the yarns are not passing throughthe reed B properly or are not being separated properly, due to slightvibrations imparted to the reed 56 or even due and the cylinder 96;- maybe 18: to;thedinerencesin thesound of theyarns passing through the.reed.

Now, as the. operator rests his. forearms upon the reed56, his wristsmaybe relativelylimp and hiskfingers will, onoccasion, inadvertently moveintosthe path of the reciprocating raking fingers However,

Anotherfeature 0t is the fact thatit is compactly, designed in such\vouldwnotonly distract the view of the operator to some extent. butwould also cause fatigue of the operator with the result that theoperator would) not operate the quilling machine with normal efliciency;
